When you’re craving a burger, nothing else will do. No need to deprive yourself! Celebrate Memorial Day with this copycat recipe of the legendary “In N’ Out” burger… metabolic style. Homemade “animal style” sauce, caramelized onions, and perfectly cooked burgers, all wrapped in crunchy organic lettuce.
Prep Time: 10 min.
Cook Time: 15 min.
Total Time: 25 min.
- 1 lb. grass-fed ground beef
- 1/2 teaspoon sea salt
- 1/2 teaspoon black pepper
- 2 tablespoons avocado oil, divided
- 2 large onions, finely sliced
- 16 dill pickle chips
- 1 large tomato, sliced
- 1/2 cup yellow mustard
- 4 ounces grass-fed cheese, cut into slices (substitute for dairy-free cheese if needed)
- 1 head butter lettuce, for wrap
- 1/3 cup avocado oil mayonnaise
- 2 tablespoons sugar-free ketchup
- 2 tablespoons pickle relish
- 1 teaspoon monk fruit sweetener (optional)
- 1 teaspoon white vinegar
Divide grass-fed beef into eight equal-sized patties, approximately 4 inches wide, and using your hand, flatten them to around 4.5mm thick. You want the patties to be thin! Season with salt and pepper and place on a large plate. Transfer to the fridge.
Meanwhile, make the onions. In a large cast-iron skillet, add 1 tablespoon avocado oil over medium heat. When shimmering, add the onions. Reduce heat to medium-low and cook, stirring regularly, until the onions are brown, approx. 15 minutes. You will need to add water, 1 teaspoon at a time, at the 7-minute mark until the end to prevent the onions from drying out.
While the onions are cooking, make the sauce by adding all of the ingredients into a small bowl. Stir to combine and set aside. You can also use this time to prepare the vegetables and remaining ingredients.
In a separate cast-iron skillet, add the remaining tablespoon of avocado oil. Heat over medium-high heat and when shimmering, add the burgers. Cook for 2 minutes or until browned on one side. Paste a generous amount of mustard on the other side of the burger and flip. Cook for an additional minute. Top each patty with cheese and cook until cheese has melted.
Layer the burgers. In each lettuce wrap, add a patty, followed by tomato, sauteed onions, pickles, and then another patty. Top with additional sauteed onions and a generous amount of sauce. Serve immediately.
